Summary

The goal of this clinical trial is to evaluate the effectiveness of laser light therapy, known as photobiomodulation (PBM), in reducing pain after dental implant surgery. The study involves adult patients receiving a single dental implant in the upper posterior (back) area of the mouth. Participants are randomly assigned to receive PBM using either a 650 nm red diode laser, an 810 nm infrared diode laser, or a sham (inactive) laser.

The study aims to assess whether PBM therapy can reduce pain during the first three days after surgery, decrease the need for pain medication, and improve oral health-related quality of life (OHRQoL). PBM is applied immediately after surgery and again within 48 hours. Pain intensity is measured at multiple time points (2, 6, 12, 24, 48, and 72 hours), analgesic use is recorded, and OHRQoL is evaluated using a standardized questionnaire.

Conditions

  • Postoperative Pain
  • Dental Implant

Interventions

DEVICE

650 nm Diode Laser PBM

A 650 nm red diode laser applied at three points (buccal, palatal, and crestal) around the implant site using 100 mW power for 60 seconds per point (total dose 18 J). Applied immediately post-op and repeated within 48 hours. Used for photobiomodulation to reduce pain and improve healing.

DEVICE

810 nm Diode Laser PBM

A 810 nm red diode laser applied at three points (buccal, palatal, and crestal) around the implant site using 100 mW power for 60 seconds per point (total dose 18 J). Applied immediately post-op and repeated within 48 hours. Used for photobiomodulation to reduce pain and improve healing.

DEVICE

Sham Laser PBM

Identical laser handpiece applied at the same locations and durations as the active PBM groups, but without laser emission. Used to maintain blinding and simulate treatment without therapeutic effect.
